Answer 1

Given

John rode 4 kilometers on his bike.

His sister Sally rode 3400 meters on her bike.

To find:

Who rode the farthest and how much farther did they ride (in km)?

Step-by-step explanation:

It is given that,

John rode 4 kilometers on his bike.

His sister Sally rode 3400 meters on her bike.

That implies,

`\begin{gathered} Distance\text{ }covered\text{ }by\text{ }John=4km \\ Distance\text{ }covered\text{ }by\text{ }Sally=3400m \\ =3000+400 \\ =(3000)/(1000)+(400)/(1000) \\ =3km+0.4km \\ =3.4km \end{gathered}`

Since 4km is greater than 3.4km.

Then,

John rode the farthest and,

`\begin{gathered} Distance\text{ }he\text{ }rode\text{ }farther=4km-3.4km \\ =0.6km \end{gathered}`

Hence, he rode 0.6km farther than Sally.
